What is a Fistula?
A fistula is an abnormal tunnel-like connection between two epithelial-lined organs or vessels. The most common types include anal fistulas, which are abnormal connections between the anal canal and the skin near the anus. Fistulas can result from infections, inflammation, or surgery, and they often require medical intervention due to their potential to cause significant discomfort and complications.
Types of Fistulas
Fistulas can be classified based on their location and cause:
- Anal Fistulas: These occur around the anal area and are often a result of an infection in the anal glands.
- Enterocutaneous Fistulas: Connect the intestine to the skin.
- Vesicovaginal Fistulas: Form between the bladder and the vagina.
- Aortoesophageal Fistulas: Rare but life-threatening, connecting the aorta and esophagus.
Causes of Fistula
Fistulas can develop due to various reasons, including:
- Infections: Chronic infections can lead to abscess formation, which may evolve into a fistula.
- Inflammatory Conditions: Diseases like Crohn's disease are known to cause fistulas.
- Surgical Complications: Post-surgical complications can sometimes result in fistula formation.
Symptoms of Fistula
Common Symptoms
- Persistent Pain and Swelling: One of the most noticeable symptoms of an anal fistula is a constant, throbbing pain around the anus. This pain often intensifies during activities such as sitting, moving, or during bowel movements. Swelling in the affected area is also common and can be accompanied by redness and tenderness.
Diagnosis of Fistula
Initial Assessment
The initial assessment of a fistula begins with a thorough medical history and physical examination. The healthcare provider will:
Diagnostic Tests Several diagnostic tests are used to visualise the fistula tract and its internal opening:
- MRI (Magnetic Resonance Imaging): Provides detailed images of the fistula tract, sphincter muscles, and surrounding tissues. It is particularly useful for identifying the internal opening and the course of the fistula.
- Fistulography: An X-ray of the fistula using a contrast agent to outline the fistula tract. This helps in identifying the path of the fistula and any possible complications.
- Endoscopic Ultrasound: Uses high-frequency sound waves to identify the fistula, sphincter muscles, and surrounding tissues. It is valuable for locating the internal opening of the fistula.
- Three-Dimensional Pelvic Ultrasound: Offers a detailed, multiplanar reconstruction of the anal canal and sphincter anatomy. It is useful for detecting internal openings and fistula tracks with high accuracy.
- Examination Under Anesthesia: Allows for a thorough examination of the fistula tract and identification of any complications. This may include the use of a fistula probe, anoscope, or flexible sigmoidoscopy/colonoscopy to visualize the anal canal and large intestine.
These diagnostic tests are crucial for planning effective treatment and reducing the risk of recurrence.
Treatment Options for Fistula
Treatment varies depending on the type and severity of the fistula:
- Surgical Intervention: Fistulotomy or fistulectomy are common procedures.
- Seton Placement: Used to keep the fistula tract open for drainage.
- Fibrin Glue or Plugs: Minimally invasive options to seal the fistula.
Living with a Fistula
Living with a fistula can significantly impact daily life:
- Impact on Daily Life: Pain and discharge can affect comfort and mobility.
- Diet and Lifestyle Modifications: A high-fibre diet and proper hygiene can help manage symptoms and prevent complications.

Prevention of Fistula
Preventing fistulas involves a combination of lifestyle modifications and early detection to reduce the risk of complications.
Preventative Measures
- Maintaining Good Hygiene: Keeping the perianal area clean and dry can help prevent infections that may lead to fistula formation. This includes showering daily and washing the area gently when soiled.
- Managing Underlying Conditions: For patients with Crohn's disease, starting anti-TNF therapies early may be protective against fistula development.
- Dietary Changes: Consuming a high-fibre diet, drinking plenty of fluids, and taking fibre supplements like ispaghula and bran can help prevent constipation and reduce the risk of fistula formation.
- Seeking Medical Attention: Early detection and treatment are crucial to prevent complications. Patients should seek medical attention at the first sign of symptoms such as persistent pain, swelling, or discharge.
